Abstract
The utility model discloses a guiding device for preventing dust-containing gasflow from impacting equipment. A sealing flange is fixedly arranged at the outer side of the middle part of a large dust bin cylinder; a flange of a dust delivery pipe is connected with a flange arranged at one end of a pressure releasing and guiding pipe and is correspondingly connected with the sealing flange; the other end of the pressure releasing and guiding pipe is in the shape of a semi-circular pipe and is arranged in the large dust bin cylinder, and the opening of the pressure releasing and guiding pipe faces to the ground; and a short guiding plate, a mediate guiding plate and a long guiding plate are arranged at the other end of the pressure releasing and guiding pipe from inside to outside in sequence. The guiding device disclosed by the utility model can be used for preventing the dust-containing gas ash gasflow from impacting an overhaul platform and a filtering cloth bag so that the wear of the dust collecting cloth bag and the inner overhaul platform is reduced effectively, has a function of gradually reducing the pressure of the delivered dust gasflow and shunting the gasflow, is simple in structure and is convenient to maintain and change.
Description
Technical field
The utility model relates to a kind of guiding device, particularly a kind of guiding device that prevents that dust-contained airflow from impacting equipment.
Background technology
Generally use at present sack cleaner in dedusting of blast furnace gas, as Fig. 1, in the defeated grey process of large ash silo cylindrical shell 2, use high pressure nitrogen to carry out defeated ash, ash pipeline 1 is welded on large ash silo cylindrical shell 2 one side neck body walls.When high pressure draft promotion gas ash enters large ash silo cylindrical shell 2, can form spurting at ash pipeline 1 mouth of pipe, gas ash under the effect of high pressure nitrogen to the overhaul of the equipments platform 4 on ash pipeline 1 top in cylindrical shell with filter cloth bag 3 and impact and wear and tear, cause the damage of inspection platform 4 and cloth bag 3, affect the device security reliability service.
The utility model content
The purpose of this utility model is to provide a kind of guiding device that prevents that dust-contained airflow from impacting equipment, changes gas ash in the flow direction of ash pipeline mouth, avoids gas ash to inspection platform and filter cloth bag impacting.
The utility model solves the problems of the technologies described above, the technical scheme that adopts is: a kind of guiding device that prevents that dust-contained airflow from impacting equipment, it is characterized in that, the outside at large ash silo cylindrical shell middle part is fixed with tongued and grooved flanges, the flange of the flange of ash pipeline and pressure-relief flow guide Guan Yiduan connects and corresponding being connected on tongued and grooved flanges, the other end of pressure-relief flow guide pipe be semicircle tubulose be placed in large ash silo cylindrical shell and cut down.
Be provided with from the inside to the outside successively short flow deflector, middle flow deflector and long flow deflector in the semicircle tubulose of described pressure-relief flow guide pipe.
When using the utility model, when gas ash enters large ash silo under high pressure nitrogen promotes, by pressure-relief flow guide pipe cut place's step pressure reducing with to the shunting step by step of large ash silo bottom, make the gas ash major part drop on smoothly collection ash place, large ash silo bottom, avoided the gas ash of surrounding injection to the injury of ash pipeline top inspection platform and dust-removal cloth-bag.
The beneficial effects of the utility model are: this guiding device can prevent from dust-contained airflow to inspection platform and filter cloth bag impacting, and can play to defeated grey air-flow the guide functions of step-down gradually and shunting.Can effectively reduce the wearing and tearing of dust-removal cloth-bag and internal overhaul platform, simple in structure, be convenient to maintenance and change.
Description of drawings
Fig. 1 is the schematic diagram of the existing large ash silo of sack cleaner.
Fig. 2 is the utility model structural representation.
Fig. 3 is the cross-sectional view of pressure-relief flow guide pipe 5 in Fig. 2.
In figure: 1, ash pipeline, 2, large ash silo cylindrical shell, 3, dust-removal cloth-bag, 4, inspection platform, 5, the pressure-relief flow guide pipe, 6, tongued and grooved flanges, 7, short flow deflector, 8, middle flow deflector, 9, long flow deflector.
Embodiment
The utility model is described in further detail below in conjunction with drawings and Examples, referring to Fig. 2 and Fig. 3, a kind of guiding device that prevents that dust-contained airflow from impacting equipment, it is characterized in that, the outside at large ash silo cylindrical shell 2 middle parts is welded and fixed and is provided with tongued and grooved flanges 6, the flange of the flange of ash pipeline 1 and pressure-relief flow guide pipe 5 one ends connects and corresponding being fixedly connected on tongued and grooved flanges 6, the other end of pressure-relief flow guide pipe 5 be semicircle tubulose be placed in large ash silo cylindrical shell 2 and cut down.
Be provided with from the inside to the outside successively short flow deflector 7, middle flow deflector 8 and long flow deflector 9 in the semicircle tubulose of described pressure-relief flow guide pipe 5.
Embodiment:In Fig. 2, pressure-relief flow guide pipe 5 stretches into the inside of large ash silo cylindrical shell 2 by tongued and grooved flanges 6, with cut one side down, and is fixedly connected with tongued and grooved flanges 6, and ash pipeline 1 is connected and fixed with pressure-relief flow guide pipe 5.As shown in Figure 3, the semicircular pipe pars intramuralis of pressure-relief flow guide pipe 5 welds from the inside to the outside successively and has been provided with short flow deflector 7, medium-sized flow deflector 8, the long flow deflector 9 that stops the dust-contained airflow effect.After dust-contained airflow enters pressure-relief flow guide pipe 5, at first contact with short flow deflector 7, from the cut pressure release with shunt, dust-contained airflow after step-down continues to contact with medium-sized flow deflector 8, and pressure release and shunting again contacts with long flow deflector 9 at last, oarse-grained dust is under the flow deflector effect, fall into collection ash place, large ash silo bottom from cut, fine dust is adsorbed by dust-removal cloth-bag 3 with low-pressure air current, avoids the high pressure dust-contained airflow to impact dust-removal cloth-bag 3 and inspection platform 4.
Claims (2)
1. one kind prevents that dust-contained airflow is to the guiding device of equipment impact, it is characterized in that, the outside at large ash silo cylindrical shell middle part is fixed with tongued and grooved flanges, the flange of the flange of ash pipeline and pressure-relief flow guide Guan Yiduan connects and corresponding being connected on tongued and grooved flanges, the other end of pressure-relief flow guide pipe be semicircle tubulose be placed in large ash silo cylindrical shell and cut down.
2. according to claim 1ly a kind ofly prevent that dust-contained airflow to the guiding device that equipment impacts, is characterized in that, be provided with from the inside to the outside successively short flow deflector, middle flow deflector and long flow deflector in the semicircle tubulose of described pressure-relief flow guide pipe.
